Application filed January 25, 1926. Serial No. 83,701.

One object of my invention'is to provide an improved form of heating a dwelling, or the like, by electrical power,

Another object is to provide with a hot water tank and' heating system, fed therefrom, improved means for forcing a circulation through the entire system.

With these and incidental objects in view, the invention consists of certain novel features of construction and combination' of parts, the essential elements of which are hereinafter described with reference to the drawing, which accompanies and forms a part of this specification. The drawing represents a diagrammatic sectionalside elevation of a dwelling house equipped with my improved heating system. In the drawing the hot water tank 1 has a connection 2 to the city water supply 3 and also a connection 4 to the electrical heater 5 and as this heater is similar in general construction to that descfiigergl in my co-pending application, Serial No. 631, it will not be further described herein.

This heater is connected at 6 to a circulat-' ing pum 7, driven by the motor 8 and the intake 0 the pump 7 is connected by the pipe 8 to the riser 9 from which the radiator 10 is tapped oii on the first floor and the 80 radiator 11 on the second floor. The two radiators are connected by the pipe 12, which returns at 13 to the tank 1'.

The motor 8 and'the heater 5 are connected to the switch 14 through the mercoid switches 15 and 16 so that even though the I switch is closed to supply power to the system, the-opening of the circuit at either of the mercoid switches 15 or 16' will cut the current ofi from both. the motor and the heater.

The mercoid switches are of the thermostatic t they w1ll not be further described, except to state that the one 15 is settable to be actuated at a given temperature so as to control the temperatureof the room, while the one 16 is set at a temperature such as 180 to prevent the water iii the tank 1 ever gettingabove this predetermined temperature. The

150 tank is also provided with; an ordinary safe- 3y valve 17,. which opens the tank to the rain pipe 18, a thermometer 19 to show the temperature of the water and a pressure gauge 20. While this tank might be con-- 5! nected to an open water tank in the attic the air tank 22, so the water in the tank will e and as their action is well known,

of the house, it is much better in m inventron to have a pipe connection 21 which leads upwards from the tank and then down into always be under pressure, as in the ordinary pressure system of hotv water heating; The Y customary drain 23 is providedfor releasmg any water that may get into the air tank 22; The pump 7 is of ordinary construction, but is. preferably of such type that a cer tam amount of thermo circulation can take place through the pump when it is not runn1ng.- v With the system described and shown, it is evident that when the motor is running, the water isforced through .the heater 5 which heats it to a high temperature and that this hot water then passes into the tank 1 and from this tank 1 out to the heating system under the drive of the, pump 7, so that a forced circulation of water is effected throughout the entire system, the returning water is, of course, the coldest in the system and this is brought into the intake of the ump 7 and then passed into the heater to e re-heated. By placing the pump at this partlcular point wlth respect to the heater, the heater does not need to handle as hot water as would otherwise and as the water 8 1 is moving through the system at all times, the water that goes to the radiators is practically the same tem erature as when it leaves the heater, so t at the radiators can be brought up to the proper temperature in '90 a minimum amount of time. r

The tank 1 is insulated so that when th heater is cut ofi, the heat will not radiate from the tank. .Furthermore, after the pump is cut oif and the heater is cut ofi, therewould still be a thermo circulation of water from the tank through the system and back through the pump and heater so that the temperature of the radiators will be with water and. free from obstruction, when in operation, so that circulation will continue, by convection, when the pump is idle, 319 and means for, maintaining a constant air pressure in the system.
